T0 WHOM IT MAY CONCERN:

Be it known that I, GEORGE F. PARTRIDGE, of Adrian, in the county ofLenawee, and State of Michigan, have invented a new and usefulImprovement in Corn-Planting Machines; and I do hereby declarethat thefollowing is an accurate description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,and making apart of this specification.

Figure 1 is a perspective view of my machine, looking from the rear.

FigureZ is an interior view of one ofthe hoppers and spout partly insection.

The same letters indicate like partsr in each figure.

The nature of this invention is to secure, by proper mechanism. theaccurate dropping of corn inplanting in one or more rows, as may bedesired.

In order to accomplish this object, I attach, in the ordinary way, thewheels A to the axle B, to which is attached the frame C, which carriesthe working parts of the machine. Forward of the axle, and midwaybetween the Wheels A, works or rotates the wheel D, upon a proper shaft,whose journals work in suitable boxes or holes in the parallel bars E.This wheel D is provided with projections F upon its sides, set atrequired distances apart, to govern the distance between the hills. Uponeach end of the front bar G, and also in thecentre of its length, Ifasten the hopper H, provided with a horizontal and perpendicular spout,I. Fitted to and working in -the horizontal partof this spout, is aslide, K, provided with a suitable slot or opening, J, of suiicient sizeto receive as many kernels of corn as isvproper to be planted in onehill. Near the lower end oi' the perpendicular part of the spout, Ipivot the valve L, which, when closed, entirely fills the interior ofthe spout. At one end of the slide K, I fasten a staple, or other properdevice, M, which holds and governs the motion of the bent or elbowedlever N, to which is attached the connecting-rod O, which gives motionto the bell-crank P, to which is rigidly attached the valve L. To theopposite end of the slide K is attached a connecting-rod,' which passesunder the shield. R, and which connecting-rod is attached to the arms S,upon the outer ends of which are hung the bent or elbowed levers T,which, at the elbow, are pivoted to the bars E, in such a manner thatthe shorter arms of the levers will engage with the projections F on thewheel D.

By this arrangement, the forward motion of the Wheel D compels theprojections F on its sides to engage with the bent or elbowed levers T,giving motion, a vibrating one, tothe arms S, the connecting-rods underthe shield R, and the slide K, so that, as the slot .I is under thehopper I-I, it is filled with the proper proportion of seed. The reversemotion of the above parts causes the slide K to move in the oppositedirection, carrying the slot J along the horizontal, to and over theperpendicular part of the spout I, when the seed drops through the slotinto the valve L, which is closed. When the slide K returns to thehoppers for a fresh supply of seed, it compels the bent or elbowed leverN, by means of the connecting-rod O and bell-crank P, to open the'valveL, and allows the seed to drop so short a distance to the ground thatthe seed will not he scattered.

Attached to the axle B, and to the parallel bars E, and-surmounting thesame, is placed the shield U, to which is attached the drivers seat V.To the front part of the shield is pivoted the bent or elbowed lever W,which is connected, by a proper rod, X, to the ends ofthe bars Y, theother ends of which are attached rigidly to the bends Z of the pole 3,which is attached to the hounds 4 by the rod 5 in thc usual manner.

This last-described apparatus is for the purpose of raising the wheel Dand the entire front part of the machine from the ground, when desired,and the lever W may be held in' position by the hooked standard 6, whichis firmly fastened to the axle B.

7 are cultivator-teeth, attached to the front bar G, in any proper way,so that they will open the ground directly in front of the spouts I,while all the wheels, A and D, are so arranged that they will track uponthe furrows opened by the teeth 7, and cover the seed when dropped.

8 is a diagonal scraper, firmly fastened to the axle B, in such a manneras to keep clean the face of the wheel D.

9 are lugs upon the sides of the face of the wheel D, and theirimpression upon the ground, as the wheel passes over it, marks theposition of the rows planted.

' operating substantially as and for the purposes here-inspeeified.

What I claim as my invention,"and desire to secure by yLet-ters Patent,is-

' 1. The hopper H, horizontal and perpendicular spout l', slide K, valveL, lever N, connecting-rod O, bellcrank P, arms S, levers T, all beingoperated by the projections F uponthe sides of the wheel D, whencoustructed'andrarranged substantially as herein set forth.

2. The lever W, rod X, bars Y, in connection with the bends Z, pole 3,hounds 4, and rod 5, when Operating substantiallyas and for the purposeherein described. l

3. Thel combination and, arrangement of the above-named parts withwheelsA A and D, axle B, frame C,

parallel bars E, front bar G, standard 6, cultivatOr-teeth 7, scraper 8,lugs 9, when constructed, arranged, and
